Snoots

A snoot is an optical accessory that narrows the beam of a strobe or video light. It is used in underwater photography for macro, selective lighting, and background control.

Snoots for underwater strobes and lights

A snoot is a device that restricts and channels light from a strobe or video source. Underwater photographers use it to illuminate a defined subject area while reducing background exposure.

By controlling the beam, snoots make it possible to highlight details in small marine life. For example, only the head of a nudibranch can be illuminated while the rest remains in shadow.

Technical considerations when using snoots

Snoots change the shape and size of the light beam; beam diameter and fibre setup define the output. Precision positioning is required.

• Flip snoots for quick positioning under water
• Fibre snoots designed for macro applications

Types of snoots and their applications

Flip snoots can be moved in and out of position rapidly, which makes them practical when alternating between standard and narrow beams during a dive.

Fibre snoots transmit light through optical cables to produce very concentrated spots. They are valued in macro photography where subject isolation is essential.

Usage guidance for underwater macro photography

Snoots are mainly used to isolate the subject from the background. This allows better visibility of fine structures in small organisms without distracting surroundings.

They are also employed to reduce light spill. For more setup information, see related guides on strobes & lights and underwater accessories.

• Restricts beam to a narrow spot
• Flip models allow fast repositioning
• Fibre designs suit close-up imaging
• Helps reduce backscatter in photos
• Improves subject-background separation
